Flyhalf Nicolas Sanchez was named as Juan Martin Hernandez’s replacement for Argentina’s Test against the Springboks in Mendoza on Saturday.

Bordeaux-based Sanchez will feature in the No 10 jersey after Hernandez suffered a hamstring injury during midweek training. Sanchez has only played three Tests, so the Pumas will lose plenty of experience in the backline for their first home game of the Rugby Championship.

Meanwhile, coach Santiago Phelan also announced his bench, which includes dropped fullback Lucas Amorosino.
